CLUTCH-OPERATING MECHANIS M FOR- WlNDlNG-DRUMS.

SPECIFICATION forming part of Letters Patent N 0. 712,242, dated October 28, 1902.

Application filed March 1,1902.

T aZZ whom it may concern:

Beit known that I, STOCKTON BARTRON, a citizen of the United States, and a resident of Stroudsburg, in the county of Monroe and State of Pennsylvania, have invented a new and Improved Clutch-Operating Mechanism for Winding-Drums, of which the following is a full, clear, and exact description.

This invention relates to improvements in devices for moving a winding-drum into operative connection with a driving-wheel and for disengaging it therefrom; and the object is to provide a simple mechanism by means of which the adjustments may be quickly made while the driving-shaft is moving in its winding direction.

I will describe a clutch-operating mechan ism for winding-drums embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal section of a clutchoperating mechanism embodying my invention. Fig. 2 is a plan view of a draw-shaft employed. Fig. 3 is a section showing a modification. Fig. 4 is a section on the line 4 4 of Fig. 1, and Fig. 5 is a section on the line 5 5 of Fig. 1.

Referring to the driving-shaft, to which is rigidly attached a driving-wheel 11, here shown in the form of a gear-Wheel, and loosely mounted on the shaft is a winding-drum 12. On oneside of the driving-wheel 11 is a clutch member consisting of a rim 13, havinga beveled outer surface to engage with a corresponding beveled surface on the inner clutch member 14 on one end of the drum 12.

For a portion of its length the shaft 10 is made tubular to receive a draw rod or shaft, here shown as in the form of a tube 15. At its inner end this draw rod or shaft has a transverse opening through which a crosshead 16 passes. This cross-head has link connections 17 with a collar 18, engaging in an annular channel formed in the hub-19 of the winding-drum. The ring or collar 18 is drawings, 10 designates a auxiliary rod.

preferably made in two sections, so that it may be readily applied or detached. In Fig. 1 I have indicated but one of the sections. It will be noted in Fig. 1 that the shaft 10 has outwardopenings through which the cross head 16 passes, and these openings are sufficiently long to permit of a movement of the cross-head lengthwise of the shaft.

One end of the shaft 10 has a bearing in a pillow-block 20, and extended through the draw shaft or rod is a thrust-rod 21. Theouter end of the draw-shaft 15 extends into and has a bearing in the front wall of a yoke 22, which, as indicated in Fig. 5, is made in the form of a cup to contain oil. The said draw-shaft 15 has a flange at its end to engage against the inner surface of the yoke. Having a bearing in the opposite wall of the yoke is an auxiliary thrust-rod 23, and at its portion within the yoke 22 the said auxiliary thrust-rod is provided witha collar or flange to engage against the inner wall of the yoke. It will be noted that the auxiliary thrust-rod 23 engages at its end closely against the end of the rod 21, and as the rod2l may rotate relatively to the rod 23 the oil in the yoke 22 will keep the connection lubricated, and it will also lubricate the connection between the draw-rod l5 and its bearing in the yoke.

Mounted on the auxiliary rod 23 is an externally-threaded sleeve 24, which engages with an interior thread formed in a casing25, bolted or otherwise secured to the pillowblock, and this casing, it will be noted, in-. closes the yoke 22. This sleeve 24is practically a portion of the auxiliary rod23. 'It is employed, however, to take up or adjust'any wear that may occur in the bearings of said theinner end of the rod and a jam-nut 26,

engaging with thethreaded'portion of the auxiliary rod and bearing against the outer end of the sleeve 24, and also attached to the outer end of the sleeve 24 is an operating-lever 27.

It is therefore clamped on the auxiliary rod between a shoulder formed at move the auxiliary shaft carried by the sleeve 24 outward. This auxiliary shaft will cause the yoke 22 to move with it, and consequently the draw-shaft 15 by drawing upon the cross head 16 will move the winding-drum out of engagement with the clutch of the drivingwheel. To engage the clutch members, the lever 27 is to be operated to force the auxiliary rod inward, and this rod will obviously force the rod 21 inward, which by bearing at its inner end against the cross-head 16 will move the cross-head, so that the clutch member 14 will engage with the clutch member 13.

In Fig. 3 I have shown the device as well adapted for small winding-drums or where great power is not required. In this arrangement the driving-shaft 10 has its hollow portion extended through the hub 28 of the winding-drum, and a rod 29 extends into this hollow portion, which answers both to move the winding-drum to clutch position or to move it therefrom. At opposite sides of the hub 28 the shaft 10 is provided with transverse openings, and the rod 29 is also provided with transverse openings. A pin or cross-head 30 extends through said openings at one side of the hub, and a similar pin 31 extends through the openings at the opposite side of the hub. Between the pin or cross-head 30 and the hub is a ring 32, while a similar ring 33is placed between the pin or cross-head 31 and its side of the hub. The operation of this device is substantially as before described in connection with Fig. 1. However, as stated, the rod 29 performs two services, moving the drum in both directions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
